The trend of adopting more and more wireless mobile computers and smartphones has changed our way of living. Those devices heavily rely on the underlying wireless network systems to provide adequate communication support. As streaming audio and video becomes norm, the requests for stringent maximum end-to-end latency and minimum bandwidth make the networking process more difficult. Quality of Service...
The area of wireless ad hoc networking has been receiving increasing attention among researchers in recent years. NS2 is the most common simulator which is used to simulate wireless ad hoc networks. But, NS2 does not scale the simulation well, where there are a large number of nodes in a simulation area. In this paper a geometric approach is proposed targeting the optimization of the area that exists...
We use a cellular automaton analogy to simulate a large scale wireless ad-hoc network. This approach combines mobility in its simplest form with some fundamental attributes of radio propagation and enables us to examine the communicative properties of the network which would not otherwise be accessible. The analysis shows that there is an optimal network density for which the throughput of the network...
Nowadays, a lot of research efforts and technical papers are done on ad-hoc networks and wireless local area networks (WLAN). Recently, however wireless mesh networking is attracting significant interest from academia, industry, and standard organizations because it is offer several favorable characteristics such as dynamic self-organization, easy maintenance and reliable services. A network with...
Simulation methods have become an integral part of almost all aspects of networking research and particularly in the area of wireless networks. Any new protocol or methodology that is proposed for wireless networks almost always will be demonstrated using simulations. However, there is little evidence that existing models of physical layer signal propagation and signal strength calculations produce...
